Programmable System-on-Chip (PSoC) Devices Combine Low-Power Digital and Instrumentation-Quality Analog Blocks, Flash, SRAM, M8 MCU, Clock–for under $2

Cypress MicroSystems Inc., a subsidiary of Cypress Semiconductor Corporation, today announced production shipments of an advanced analog family of its award-winning Programmable System-on-Chip (PSoC) mixed-signal array. PSoC devices are high-performance, field-programmable, mixed-signal arrays for high-volume embedded-control functions in consumer, industrial, office automation, telecom and automotive applications.

The new CY8C27x device family provides highly stable, instrumentation-quality analog performance including rail-to-rail inputs; programmable gain; 14-bit analog-to-digital converters (up to four independent converters are available in a single PSoC device); exceptionally low noise, input leakage and voltage offset, along with rich digital functions including an 8-bit microcontroller core.

Containing over 100 reconfigurable analog and digital library components created from 12 fundamental analog and 8 digital blocks, PSoC CY8C27x devices are true systems on a chip. Each contains a 24 MHz 8-bit microcontroller unit (MCU); 16 kbytes of flash memory; 256 bytes of SRAM; an 8×8 multiplier with 32-bit accumulator; power and sleep monitoring circuits; and a precision real-time clock.

CY8C27x devices eliminate the need for expensive non-integrated analog components such as instrumentation amplifiers, filters (Bessel, Butterworth, and elliptical up to eight poles), RMS/DC converters, programmable-gain amplifiers, and thousands of other analog components.

With a noise threshold of 70 nV/rtHz and an analog offset voltage of 6 mV digitally trimmed to less than 100 ?V, the enhanced PSoC devices bring the advantage of high-quality analog components to a single, inexpensive, easy-to-program mixed-signal device.

In addition to greatly improved analog performance, the new generation PSoC devices also contain dozens of digital and system-level enhancements, including hardware I2C communications for reduced MCU overhead; increased interconnects for data and clocking; synchronous, asynchronous, and latched deadband modes to enable demanding motor-control applications; logic; and numerous additional I/O modes for improved drive and EMI performance.

With a typical sleep current of just 3 uA, PSoC offers the lowest power consumption in the industry for flash-based applications. The 3 uA specification includes operation of the sleep timer, watch dog circuits, and power supervisor functions, all of which are ed quired in most flash-based embedded designs.

The CY8C27x PSoC family is in production now and contains eight family members ranging from an 8-pin PDIP to a 48-pin MLF/QFN.
